I am working on a Simplex Amateur Radio Repeater. Operation is such that when a signal is detected, the recorder starts and a recording timer is started. When the signal is no longer detected or the recording time limit has elapsed, the radio is set to transmit and the recorded audio is played back and transmitted. I need a way to to detect, programmatically, when the playback has completed, so the transmitter can be turned off and the repeater reverted to listening for in incoming signal.
